Abstract

In this report, we propose a method which generates a high-quality subdivision surface from mesh data satisfying boundary conditions. We estimate second cross-derivatives at boundaries and construct a control mesh so that the interpolated shape is supposed to be trimmed from an extended shape at the boundary. At sharp features, we introduce a subdivision rule in a similar manner to Hoppe et al., which makes a crease or boundary correspond with a specified curve.
